Just like the previous seasonfinales, the "Who won? Who's next? You decide" sequence at the end was omitted.

Though, the announcer could still be heard singing "Epic Rap Battles of History" at the end.

Instead, it ended with a projection of all the battles from Season 3, which was also done with Season 2 in Rasputin vs Stalin.

This is the first time it contained footage from another season at the end, as the season finales for each season could be seen at the bottom advertising their respective seasons.

Production

The cover art for this battle is the first one to have the rappers in front of the ERB logo, not behind it.

The cover art also features the greatest number of rappers on the cover at once, with eight, beating Mario Bros vs Wright Bros' previous record of four.

Link Neal's character, Leonardo da Vinci, had the most solo lines over the course of the battle, having eight in the first verse alone, while the other Artists had four, plus one in the second verse, for nine total.

This is the first season finale to include a guest rapper, as well as two guest duos.

During their introduction, Peter voiced Michelangelo. During their first and second verses, Lloyd took the role of Michelangelo.

During their first verse, Peter voiced Leonardo. During their second verse, Leonardo's first solo line was said by both Lloyd and Peter in unison. Though the rest of Leonardo's lines were said by his original voice actor: Peter.

During a few different lines, the edge of Leonardo (Turtle)'s shell turned orange. This is due to the use of a blue screen for the TMNT.

While Michelangelo (Turtle) says, "Ain't here, dudes!", three Raphaels could be seen behind him, but one was holding Donatello's staff and the other two had Leonardo's swords.

This could be a reference to the early TMNT comics where they all wore the same color headbands.

Leonardo and Donatello's headbands, however, were the same shade of red-orange as their headbands in the acapella Behind the Scenes video, as they were changed to blue and purple in editing, so its status as an error is debatable.

During the line, "You guys draw more dicks than New York Pride!", Donatello (Turtle) was seen with a sai in his belt, which is used by Raphael (Turtle).

During the video's endslate, each turtle's shell changes to their respective signature color.
